PINE RIDGE, S.D. (AP) - The Oglala Sioux Tribe says Chief Oliver Red Cloud, a descendant of the legendary Lakota Chief Red Cloud, has died at the age of 93.

Tribal spokeswoman Toni Red Cloud, who is Oliver Red Cloud's niece, says her uncle died Thursday in a Denver hospital surrounded by family. Memorial arrangements are being planned.

Family members in a statement say Oliver Red Cloud was a powerful orator about obligations each nation had to the other in keeping peace during modern times. They say he was the leading statesman for keeping peace between Lakota, Cheyenne and Arapaho people.

Chief Red Cloud was an Oglala Lakota signer of the 1868 Fort Laramie Treaty peace agreement with the United States.
